"According to updated estimates, federal budget revenue will increase by more than 900 billion rubles ($38.2 billion) to almost 9 trillion rubles ($382 billion)," Putin told a government budgetary commission.
Putin said the Russian government was able to increase the 2008 budget largely due to economic growth in the country, in addition to the high global price of oil.
Net capital inflow into Russia reached a record $82.3 billion in 2007, almost double the previous year's figure, Russia's Central Bank earlier said.
Net capital inflow into Russia hit $19 billion in April and is expected to reach $18 billion in May, the finance ministry earlier said.
Russia's GDP grew 8.4% year-on-year in April and 8.3% in the first four months of 2008, the economics ministry earlier said.
